PORTABLE ELECTRIC LAM-P.

Application filedNovember 15, 1926. Serial No. 148,384.

My invention relatesto improvements in portable electric lamps, and hasfor its primary object a lamp intended for use on automobiles in whichan electric light bulb is used and which bulb is protected in such a wayby means of a cage so that the, bulb will be reasonably safeguardedagainst heavy base so that the same will stand up right andnot be liableto upsetting, the base being provided with an electro-magnet which isthrown incircuit at the same time that the bulb is illuminated so thatthe lamp will adhere in anyposition to any material which will respondto magnetic action. This renders my device especially applicable toautoadhere at practically any place or at least I any metallic part ofthe automobile so that road-side repairs, such as tire changing and thelike and also adjustments to the engine underneath the hood, can bereadily made and without the danger of fire.

In the drawings:

Fig. 1 is a side elevation of my device.

Fig. 2 is a top plan view of the same with the bulb removed;

Fig. 3 is a top plan view of Fig. 2 with the cage moved away so that abulb can be placed in position; and

Fig. 1 is a vertical section taken on the line H of Fig. 1.

In the construction of my device, I employ a metallic base 5. This baseis hollow and contains an electro-magnet 6. This electromagnet is of theusual construction and has the central magnetic core 7. Resting on thebase 5 is a disk of insulating material 8, which carries electriccontacts 9 and 10. The base and electro-magnet are secured to gether bymeans of a screw 11. Secured on top of the base 5 is a cylindricalmember 12, which isprovided with a concentric cylindrical portion 13.This portion is of lessdi than the cylindrical portion 12 The mobilesbecause, as aforesaid, the lamp will cylindrical portion 13 carries alamp socket .1 1 which is of the usualbayonet joint'type common toautomobile light sockets.

Carriedbythe reduced portion 13 are; a plurality of guard members 15,16and 17, which are substantiallyof U shape and which form protecting cageforlthe bulb 18. The member 15 is-provided with an outwardly bentportion. 19, and the member 17 with an inwardly bent portion 20. The

members 15, 16 and 17. have portions 21 passing through the cylindricalportion 13, the ends of these portions 21 being upturned jasindicated bythe numeral 22 so that the same are lockedin position in the cylindricalprojection 13, and, by means of the recess 2O orinwardly bent portionand the outwardly" bent portion 19, the members 15, 16

and 17 can be assembled into a rigid cage as illustrated in Figs. 1 and2 completely surrounding the bulb so that in the event that the fixture.should drop, the bulb will be protected against ibreakagel' 1' Thecy1'in drical housing 12 is secured to the basev 5 by means of screws23. The housing 12 is also provided with an opening through whichelectric conductors 2 1 and 25 pass.

These conductors are secured to binding posts 26 and 27, which connectthe. conductors to the contacts'9 and 10! The binding posts also carryelectric conductors 28 and 29, which complete the'circuit through theelectro-magnet. It is to be understood, of course, that the free end ofthe conductors 2 1 and 25 are provided with suitable means so that theycan be readily attached to a source of electrical energy. It is furtherto be understood that while I have shown thebulb 18 as being of thedouble contact type, and I may, without departing from the spirit of myinvention use the single contact, this however falls within the skill ofany electrical mechanic and therefore is not shown or described, the Qessential feature of my device being to provide a portable electriclamp, which can be readily attached to and detached from v'a-' riousmetallic parts of an automobile so as to serve as a trouble light, itsuse not being restricted only to making repairs but also in the event ofthe failure of'a tail light or one of the headlights since theelectro-magnet made strong enough. to hold the light iii) Withoutremoving the cage from the eye lindrical member so that a bulb can bereadily inserted and without loosening any nuts or screws which securethe cage in position.

It i will be observed from my foregoing description that the cage asmade by me is a knocked-down cage and that itcan be knocked downandre-asse nbled Without removing the cage from the base or from. thecylindrical member. s

' Having fully described my invention,

What I claim is ,1; A portable electricv lamp comprisinga hollow, base,a cylindrical member Carried by said base, an electric lampsocket'secured within said member, a plurality of members haVing-inturnedends pivotally secured at both, ends in the u'pper end of saidcjflindrical member, said members adapted to be swung outward foraffording free access to said socket for the insertion of abulb andtoward each other for forming a protectingcage for said bulb, and; meansfor detachably holding said members. together when forming thecage. 7 Y
